Description

Technical Field

[0001] This application relates to the field of burner technology, specifically to a tooling for manufacturing a horizontal flow burner air distribution system. Background Technology

[0002] During the production of asphalt concrete mixing plants, burners are used to dry aggregates. The air distribution swirl plate is crucial for stabilizing the flame, promoting the mixing and combustion of fuel gas and air, and matching the flame and drum shape. In horizontal flow burners, the primary and secondary air are not separated. The secondary air flows directly, while the primary air rotates through the swirl plate to form a recirculation zone to ensure ignition. However, dimensional errors are prone to occur during the manufacturing of the swirl plate, which can affect the flame quality.

[0003] The air distribution swirl system consists of swirl plates, fixed rings, support rings, and support rods. During manufacturing, the concentricity of the swirl blades and the support ring, as well as the angle control of the swirl blades, urgently need to be addressed. Summary of the Invention

Detailed Implementation

[0051] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory, and should not be used to limit the scope of protection of this application.

[0052] Please refer to Figure 1-3 This embodiment provides a manufacturing fixture for a horizontal flow burner air distribution system, including a workbench 100, with a support mechanism at the bottom and a support platform 110 at the top; a central fixing screw 200, which is fixedly installed on the support platform 110 for mounting a swirl plate 300 and a support ring 310; a positioning mechanism, which is sleeved on the central fixing screw 200 for positioning and fixing the swirl plate 300 and the support ring 310; and a limiting mechanism, which includes multiple limiting mechanisms that can be raised and lowered and installed on the workbench 100, abutting against the top surface of the swirl plate 300 to limit the rotation of the swirl plate 300.

[0053] In this embodiment, the swirl plate 300 first follows... Figure 3 As shown, a complete plate is cut into parts, including an inner ring 301, an outer ring 302, and a blade 303 located between the inner ring 301 and the outer ring 302. It should be noted that the blade 303 is not completely cut off from the inner ring 301, while the blade 303 is not completely cut off from the outer ring 302, leaving a 5-7mm connection. After the cutting is completed, the blade 303 is manually twisted for the first time before being installed on this fixture.

[0054] In this embodiment, the support mechanism at the bottom of the workbench 100 can adopt multiple height-adjustable support legs; these support legs can be threaded adjustment legs, and by rotating the adjustment nut, the height of the workbench 100 can be flexibly adjusted to adapt to the height of different operators and the needs of the working environment.

[0055] In this embodiment, the support platform 110 is installed on the top of the workbench 100, providing a stable mounting base for the central fixing screw 200; the central fixing screw 200 is vertically installed on the support platform 110, ensuring that the swirl plate 300 and the support ring 310 remain vertical after installation, providing a precise reference for subsequent processing; the positioning mechanism is sleeved on the central fixing screw 200, and when installing the swirl plate 300 and the support ring 310, the positioning mechanism accurately determines their positions on the central fixing screw 200, ensuring their concentricity.

[0056] In this embodiment, multiple limiting mechanisms are installed on the worktable 100. When the blades of the swirl plate 300 are being torsional processed, the top of the limiting mechanism is in close contact with the top surface of the swirl plate 300, effectively preventing the swirl plate 300 from flipping over due to the torsional force during processing, thus ensuring processing accuracy.

[0057] In a preferred embodiment, the workbench 100 and the support platform 110 are connected by adjusting bolts 111; the number of adjusting bolts 111 includes three, and they are evenly arranged around the central fixing screw 200; the support platform 110 is provided with matching countersunk holes corresponding to the adjusting bolts 111; the workbench 100 is provided with matching through holes corresponding to the adjusting bolts 111; the adjusting bolts 111 are installed in the countersunk holes, with one end penetrating through the through holes, and are locked to the support platform 110 and the workbench 100 respectively by matching first nuts.

[0058] In this embodiment, the workbench 100 and the support platform 110 are connected by three adjusting bolts 111, which are evenly distributed around the central fixing screw 200. In actual operation, when a slight tilt is found in the support platform 110, it can be finely adjusted by adjusting the bolts 111. For example, if a certain corner of the support platform 110 is too low, the first nut on the adjusting bolt 111 near that corner can be loosened, the adjusting bolt 111 can be turned upwards a certain distance, and then the first nut can be tightened to raise that corner of the support platform 110 until the support platform 110 reaches a horizontal state. The adjusting bolts 111 are installed in the countersunk holes of the support platform 110, with one end penetrating through the through hole of the workbench 100. This design can ensure the stability of the adjusting bolts 111 and prevent the adjusting bolts 111 from protruding from the surface of the workbench 100 and affecting other operations. The dimensional accuracy requirements of the countersunk holes and through holes are high and must be strictly controlled within a certain tolerance range to ensure that the adjusting bolts 111 are installed tightly without any shaking.

[0059] In a preferred embodiment, the central fixing screw 200 is a variable diameter screw; the support platform 110 is provided with a matching stepped hole corresponding to the central fixing screw 200 for positioning and installation with the central fixing screw 200; the diameter of the stepped hole is relatively small at the end near the worktable 100; the central fixing screw 200 is installed in the stepped hole, and the end with the relatively small diameter passes through the worktable 100, and is locked and fixed to the support platform 110 and the worktable 100 respectively by lock nuts.

[0060] In this embodiment, the central fixing screw 200 is a variable diameter screw, which is installed in conjunction with the stepped hole on the support platform 110. During installation, the smaller diameter end of the central fixing screw 200 is inserted into the step hole of the support platform 110 near the worktable 100 until the screw is fully installed. After installation, the central fixing screw 200 is locked and fixed by locking nuts at the bottom of the support platform 110 and the bottom of the worktable 100 respectively. In actual processing, the fitting accuracy of the variable diameter screw and the stepped hole has a significant impact on the installation accuracy of the swirl plate 300 and the support ring 310. Therefore, when processing the variable diameter screw and the stepped hole, high-precision processing equipment and processes must be used to ensure that the fitting clearance between the two is within a reasonable range, so as to ensure both smooth installation and the stability of the central fixing screw 200 after installation.

[0061] In a preferred embodiment, the positioning mechanism includes a positioning sleeve 210 sleeved on the central fixing screw 200; the outer diameter of the positioning sleeve 210 is a variable diameter structure, with the outer diameter of the end away from the support platform 110 being relatively small and matching the inner diameter of the swirl plate 300, for positioning and installation with the swirl plate 300.

[0062] In this embodiment, the positioning sleeve 210 in the positioning mechanism is fitted onto the central fixing screw 200. Its outer diameter is a variable diameter structure, and the outer diameter of the end away from the support platform 110 matches the inner diameter of the vortex plate 300. When installing the vortex plate 300, align the center hole of the vortex plate 300 with the end of the positioning sleeve 210 with the smaller outer diameter, and slowly fit it in until the vortex plate 300 and the positioning sleeve 210 are fully engaged. The variable diameter design of the positioning sleeve 210 allows the vortex plate 300 to quickly find its position during installation, and ensures the concentricity of the vortex plate 300 and the central fixing screw 200 after installation, thus improving installation efficiency and accuracy. At the same time, the material of the positioning sleeve 210 must have a certain degree of hardness and wear resistance to ensure that the positioning accuracy will not be affected by wear during repeated use.

[0063] In a preferred embodiment, a height adjustment sleeve 220 is further provided between the positioning sleeve 210 and the support platform 110; the height adjustment sleeve 220 is sleeved on the central fixing screw 200 and is used to adjust the installation height of the vortex plate 300.

[0064] In this embodiment, a height adjustment sleeve 220 is provided between the positioning sleeve 210 and the support platform 110. In actual production, when it is necessary to adjust the installation height of the swirl plate 300, it can be achieved by replacing the height adjustment sleeve 220 with a different height. The height adjustment sleeve 220 has high machining accuracy requirements, and its inner and outer diameter tolerances need to be strictly controlled to ensure the accuracy of adjusting the installation height of the swirl plate 300.

[0065] In a preferred embodiment, a clamping sleeve 230 is also fitted on the central fixing screw 200 to press the positioning sleeve 210 onto the height adjusting sleeve 220.

[0066] In this embodiment, the clamping sleeve 230 fitted on the central fixing screw 200 may have an internal thread, thereby threadedly connecting with the central fixing screw 200. After the positioning sleeve 210 and the height adjusting sleeve 220 are installed, the clamping sleeve 230 is screwed into the central fixing screw 200. By rotating the clamping sleeve 230, the positioning sleeve 210 is pressed onto the height adjusting sleeve 220. The thread accuracy of the clamping sleeve 230 has an important impact on its clamping effect. Therefore, when machining the clamping sleeve 230, it is necessary to ensure the accuracy and smoothness of the thread to ensure that it fits well with the central fixing screw 200.

[0067] In a preferred embodiment, the support ring 310 is connected to the central fixing screw 200 via a support sleeve 240; the support sleeve 240 is a stepped bushing, the inner diameter of which matches the outer diameter of the central fixing screw 200, and the outer ring includes a mounting part with a relatively small diameter and a positioning part with a relatively large diameter; the mounting part is located at the end of the support sleeve 240 away from the support platform 110.

[0068] In this embodiment, the support ring 310 is connected to the central fixing screw 200 via the support sleeve 240. The support sleeve 240 is a stepped bushing, with its inner ring matching the outer diameter of the central fixing screw 200, and its outer ring mounting portion used to install the support ring 310. When installing the support ring 310, the support ring 310 is fitted onto the mounting portion of the support sleeve 240 to ensure a tight fit between the support ring 310 and the support sleeve 240. The positioning portion of the support sleeve 240 has a large diameter and serves a positioning function to ensure the accurate position of the support ring 310 after installation.

[0069] In a preferred embodiment, the central fixing screw 200 and the support sleeve 240 are fixed together by a second nut; one end of the support sleeve 240 abuts against the clamping sleeve 230 and the other end abuts against the second nut; the second nut is threadedly connected to the central fixing screw 200.

[0070] In this embodiment, the support sleeve 240 is installed on the central fixing screw 200, with one end abutting against the clamping sleeve 230 and the other end abutting against the second nut. The support sleeve 240 is fixed on the central fixing screw 200 by the second nut. When installing the second nut, it is necessary to tighten it according to the specified torque to ensure that the support sleeve 240 is firmly fixed and to avoid loosening during the processing.

[0071] In a preferred embodiment, the limiting mechanism includes a screw 400 fixedly installed on the worktable 100 and a pressure plate 410 installed on the screw 400; the screws 400 are arranged in pairs and are arranged radially along the swirl plate 300; one end of the pressure plate 410 is connected to the screw 400, and the other end extends above the swirl plate 300.

[0072] In a preferred embodiment, the pressure plate 410 is provided with a corresponding strip hole corresponding to the screw 400; the strip hole extends along the length direction of the pressure plate 410 and the width matches the diameter of the screw 400; the screw 400 is provided with a third nut for locking on the upper and lower sides of the pressure plate 410 respectively.

[0073] In this embodiment, the screws 400 of the limiting mechanism are fixedly installed on the worktable 100, and two are arranged radially along the swirl plate 300. When installing the pressure plate 410, the slotted hole on the pressure plate 410 is aligned with the screws 400, so that one end of the pressure plate 410 extends above the swirl plate 300. Then, third nuts are installed on the upper and lower sides of the screws 400 on the pressure plate 410 respectively. By adjusting the position of the third nuts, the height of the pressure plate 410 can be adjusted so that it is in close contact with the top surface of the swirl plate 300. In actual processing, the height of the pressure plate 410 is flexibly adjusted according to the thickness of the swirl plate 300 and the processing requirements to ensure a good limiting effect.

[0074] In a preferred embodiment, after the swirl plate 300 is installed,

[0075] First, the blade 303 is twisted a second time to ensure that the angles of each blade 303 are consistent. Specifically, the gap distance between adjacent blades 303 is measured and adjusted in conjunction with the second twist to make the gap distances the same. After the blade 303 angle is adjusted, the contact point between the blade 303 and the outer ring 302 is spot welded to ensure its strength.

[0076] Then, the support ring 310 is installed onto the support sleeve 240, and matching bolts are installed in the threaded holes on the support ring 310 to fix the support ring 310 and the support sleeve 240 relative to each other.

[0077] Then, place the two retaining rings 320 on the blades 303 of the swirl plate 300, and weld the blades 303 to the contact points of the two retaining rings 320.

[0078] Finally, the support rod 330 is welded to the fixing ring 320 and the support ring 310. After the entire assembly is completed, it needs to be sprayed with high-temperature resistant paint because it will be in contact with the flame for a long time.
